Mike Huckabee, left, is joined by his wife Janet as he addresses a victory party in Des Moines, Iowa, after being declared the winner of the Iowa Caucus. Sen. John McCain, who won the party nomination, ended up fourth. The Iowa caucuses draw outsized attention from politicians and the news media because they are first and can put a symbolic political wind behind the sails of the top finishers, making them more attractive not only to voters but also to donors who finance campaigns.
